When running ./nvm-latency-bench or other tests, the bug appears as below: [unmap_memory] Page unmapping kernel request failed: Invalid argument

This is a bug mentioned in #22

The bug appears when map A and B is created by host but when trying to unmap B mapA->vaddr == (vaddr & GPU_PAGE_MASK) can also be true
